SPECIFICATION forming part of Letters Patent No. 473,609, dated April26, 1892.

Application filed October 80, 1891. Serial No. 410,304. (No model.)Patented in England June 16, 1891, No. 10,190, and A gu t23,1891,No.14,211.

To ttZZ whom it may concern:

Be it known that I, WALTER BRAMPTON, manufacturer of cycle-saddles, ofthe firm of Brampton Brothers, of 24 and 25 Masshouse Lane, Birmingham,in the county of Warwick, England, and a subject of the Queen of GreatBritain; have invented certain new and usef ul Improvements in Saddlesfor Bicycles, Tricycles, and Such Like Purposes, of which the followingis a specification.

This invention has been patented in Eng land, No. 10,190, dated June 16,1891, and No. 14,211, dated August 23, 1891.

My invention has for its object improvements in saddles for bicycles,tricycles, and such like purposes, and is intended to greatly lessen thevibration transferred from the machine to the rider or riders, and is sodesigned as to avoid all hard parts, and so as to be flexible in everydirection, while affording a substantial seat and support to the rider.It is also so designed and constructed as to be very light indeed, andthe rider can adj ust the tension of the surface of his saddle withoutalighting and without any tool,which is a great advantage.

My invention is as follows: The frame upon which the leather seat orother surface of the saddle is supported is made of a rod of round orother steel, iron, or other metal bent round into an eye at the front toreceive the adj ustment-screw and the two ends pass back to the rear ofthe saddle, and are there attached by eyes and bolts or rivets or forcedinto holes, but in any case to the back frame or plate. The rod as itpasses along maybe bulged out to form a substantial seat for thejunction casting or plate or saddle-bar socket to slide, so as to adjust the inclination and balance of the saddle in a most simple manner.These rods may be made either quite stiff or slightly yielding underexcessive strains or in some cases the rods may be substituted by aplate to receive the leather or seat part. The surface or seat portion,whether leather or other material, is attached to the front end by meansof a plate or nut which carries a thread, into which a suitablehand-screw is fitted. The neck of this handscrew is formed conical, soas to take an easily-adj ustable bearing against the eye formed by therod before mentioned.

The head of the screwis by preference round and milled and of largediameter, so that the hand has power enough to set it while the rider isupon the machine. The back portionof the leather or saddle surface fallsconsiderably short of the length of the under frame, so as to allowsufficient room for the mounting of intermediate spiral or otherequivalent springs which are attached to the back plate by hooks or eyesor other convenient manner, and to the back end of the seat by means ofa plate or rod or cars or other convenient manner. In any case theattachments are such as to allow freedom for the elastic qualities ofthe springs connecting the back of the frame and the back of thesaddlesurface to be brought into free use. Of course the strength ofthese springs and the number of them will depend upon the strength anddesign of the saddle.

Referring to the drawings annexed hereunto, Figure 1 is a perspectiveview of the saddle as in use. Fig. 2 is a plan of the under side of thesaddle with a portion of the framerods removed for the sake of clearnessof illustration. Fig. 3 is a section through the back portion of thesaddle on the dotted line shown upon Fig. 1; and Fig. 4C is a sectionthrough the saddle-bar S,showing thesaddle-bar socket K in endelevation.

It will be seen that the surface leather or other material A is fastenedat the front end to a socket by three or other number of rivets b, andthe back part of A is fastened to the bridge-plate E by the rivets e.Be-

tween the surface A and plate E is the intermediate stout leather orother equivalent piece H, to which the spiral or other equivalentsprings M are connected by rivets and washers m or their equivalent, andthe other end of the springs M are attachedto the stout angle or otherplateR by means of similar rivets or screws 4'. The tension of thesaddle is maintained by the frame-rods T or other equivalent frame. Inthe case shown the round rod is bent to form an eye at the front end t,the back end of the rod being thrust into the sockets r on the plate R,Where they are firmly secured. This rod or frame is so bent, as shown onthe plan and elevation, that the saddle-bar socket K draws or forcesthem somewhat out of their normal shape, thus avoiding altogether, apartfrom the tighteningscrews 70, any shake; but these eye-screws k lock thesocket K in any desired positionu pon the frame bar or bars T. It willbe noticed that the ends 70 are hollowed at 70 so as to hold the bar Tvery tightly. It will be noticed that the inclination or pitch of thesaddle may be influenced by the position of the plate Kt'. e., the frontend may be raised and the back lowered, or vice versa. The frontconnection with the frame is made by the hand-adjusting screw W, whichpasses through the eye of the frame T at t and screws into the nut B,which may be of any desired shape, but the one shown is very applicable.The conical neck of this screw IV, bearing against the round rod T,gives such a small bearing-surface that the front of the saddle is mosteasy, adapting itself to the motion of the rider under exceptionalstrains, which is aquality greatly desired. Of course this shape may besomewhat modified with similar elfect. It will be evident that theupper'surface of my saddle A with the parts B E R M WV may be attachedto many other kinds of frames with similar effect as an elastic saddle.

What I claim, then, is

1. In a saddle for a bicycle or similar vehicle, the frame T, consistingof a single bar bent at t to form two diverging arms, in combinationwith a leather A, a nut B, attached to the'front end of the saidleather, an adjusting-screw W, which is straddled by the bent part ofthe said frame and engages the said nut, and devices between the saidframe and the said leather for supporting the latter, substantially asset forth.

2. In saddles for the purpose herein mentioned, the combination of thesprings M with their supporting-plates, the adjusting device WV and B,and the frame Tand saddle-bar socket K, substantially as herein setforth, and shown upon the drawings.

In testimony that I claim the foregoing as my own I affix my name in thepresence of two witnesses.

WALTER BRAMPTON.
